to sink the new I'D" shaft at the Chapin
mine, Iron Mountain, Michigan. ON the
Menominee range, through auicksand
ninty-seven feet To the ore. This shaft
has been located on the foot-wall, at the
west end OF the workings, and for some
time the successful manner OF it's sinking
has been problem To- the Chaplin mine
management, as the surface, which is
ninty-seven feet deep, liz a troublesome
quicksand, almost impossible TO sink i'm.
'D'' shaft will be circular i'm shape. will
be twenty-five feet in diameter and will
be cased up with iron castings. This will
be the first use made OF the freezing pro-
cess IN iron mining in the United States,
and the work will be watched with n
great deal OF interest. This method ig
used in sinking shafts, making excavn-
tions Tor the foundations OF bridges and
buildings and for constructing sub
aqueous tunnels, sewers, condnits, etc,
and IN TACT Tor all work of an excavating
nature IN quicksand and other water
bearing and soft soils. IL was invented
by a Mr.. Pntsch, OF Germany, and was
first successfully applied there. The
method rs undoubtedly one Of the most
valuable contributions To engineering
science apd art that has been made dur
ing the present century IL consists
SIMPLY IN freezing the material about the
space TO be excavated, and thus convert
ing IT temporarily into solid wall which
permits the excavation TO be made and
the permanent work TO be- executed with
ease and safety. In some instances the
entire mass through which the work is
To be carried, Is frozen and the work done
as IT would be in solid rock The freez-
ing rs accomplished by passing double
pipes at suitable intervals through the
material to be frozen and then circulating
BRINE, cooled IN tank 10y an ice machine
TO very low temperature, through these
pipes. In the case Of the new shaft ut
the Chaplin, the driving OF these pipes
does not come within the contract made
with the Pgtsch-Sooysmith concern.
The Chaplin Co., will drive the pipes A
ten-inch pipe will be driven, in which an
eight-inch pipe will be inserted. Twenty
five OF these have TO be put down and
the task must necessarily entail the ex-
penditure OF a great deal Of time and
money. The brine goes into the inner
pipes, which are open at the end and re-
turns through the space between the
inner and outer pipes, the latter being
closed Mt the end. The heat is thus taken
out OF the surrounding material, until il
il frozen to the desired thickness. The
returning brine flows in tank where il
is again cooled Several shafts have
been sunk by this process in Germany
through quicksand and other trouble
some materials; and one i'm Belgium, at
Houssu, TO a depth Of PA feet allquick-
sand below a depth OF thirty feet from
the surface. I'm that vicinity very large
sums OF money had been expended in
unsuccessful attempts to sink similar
shafts by other well known and approved
(. methods. The process is said 60 be an
absolute one, and the cost of works to
beexecuted by itcan be closely determined
in advance. Shafts, wells, foundations
tunnels, sewers, conduits and similar
works can be done at almost any depth
by this simple, safe and efficient method F;
and Tor such works as might cndanger
existing buildings or structures of any
kind, such as subteranean works i'm
cities, or the repairs or strengthening Of
foundations, il is peculiarly reliable aud
valuable, as all movement Of the sur
rounding materials is absolutely pre-
vented Chas. Sooysmith visited works
i'm progress by this method in Germany,
Tor the express purpose of judging Of It's
merits rs applied To very difficult en-
gineering works As a result of this
examination, the Poetsch-Sooysmith
